[PATCH 2/3] arm64: dts: armada-3720-espressobin: make use of switch irq line

[Uwe Kleine-König]

The switch's INTn line is connected to the CPU's MPP2_23 pad. Wire this
up in the device tree. Note however that up to now the
marvell,armada3710-sb-pinctrl driver doesn't support level irqs, so the
switch driver doesn't make use of this feature.
